Passive bass, relatively high output. No other pedals. Yes bass straight to 400rb works but RBI in line creates an issue even with the pad engaged. Isn't that very weird? Yes tried engaging and lowering RBI volume, but when I get the volume up from the 400rb regardless if it's...

Tech21 thanks for the answer. The weird thing is that my 400rb gets overloaded in the input stage even if the RBI isn't engaged. Just the signal passing through the RBI. Bass straight to the amp doesn't do that. RBI TS to my other amp input, fusion 550 works as it should, so the question in my...

Yes, all normal!

Yes, even I'm when volume knob on GK is minimal, adding volume from master or boost results in the same farting sound. Using the RBI straight to my fusion 550 everything runs fine. That's why the question is narrowed down to the 400rb 1. Yes that may be a solution that I wouldn't like much...

Level knob doesn't work when RBI is disengaged. There are instances I may use a pedal format preamp, so the RBI isn't always on and of course I would like a setup where I won't have to mess with the cables in the back of the rack

You mean in general right? Cause in the video the RBI isn't engaged, signal just passing raw through it

Not yet. Firstly cause I want the extra colouring of GK's preamp, secondly cause I have the dbx in the send return. So to speak that would be my dream setup, if it wasn't for the preamp overload....

Forgot to share the video!

Hello good people! To those who know the 400rb inside and out, I have this problem with my amp only when using the RBI trs output in the input of the amp. Pad is on of course. So am I to assume GK's preamp can't stand the RBI signal?

Yes it's greatly low output. I can't drive pedals without a boost up front, I would like to do that through the current preamp module if possible. Many have done it before on some newer Vari Mid modules, but can it be done in that one? Don't want to change the preamp as I like it, neither the...

Hello fellow bass players! Looking for some info on this old preamp board and if someone knows how could I increase the output through dat.
